Cerebellum Viewed in a Section of the Skull

Description

Presented as a lateral section through the male cranium, the cerebellum sits posterior and inferior to the cerebrum, tucked into the posterior cranial fossa beneath the tentorium cerebelli. Folia radiate around central cerebellar white matter, and the arbor vitae branches toward the cerebellar cortex, with the vermis positioned on the midline between the hemispheres. Anteriorly, the cerebellum relates to the fourth ventricle and dorsal brainstem, with the pons and medulla lying ventral to the cerebellar parenchyma. The flocculonodular lobe occupies the anteroinferior cerebellum near the cerebellopontine angle, close to the vestibular connections of the brainstem. Clear separation of gray cortex and white matter is the visual anchor. This cutaway is the one you want when teaching the internal organization that underlies cerebellar signs on exam. Lesions of the vermis classically produce truncal ataxia and gait instability, while hemispheric involvement skews limb coordination, dysmetria, and intention tremor, and flocculonodular pathology tracks with vertigo, nystagmus, and impaired vestibulo-ocular reflexes. The arbor vitae pattern is also a practical correlate in posterior fossa imaging, where mass effect on the fourth ventricle and brainstem helps explain obstructive hydrocephalus and early cardiorespiratory compromise in cerebellar hemorrhage or tumor. A tight space. Use this artwork in neuroanatomy and neurology teaching blocks to pair gross sectional anatomy with cerebellar functional topography, and in clinical texts discussing posterior fossa syndromes, cerebellar stroke, or midline medulloblastoma versus hemispheric metastasis. It also fits patient-facing neurosurgical materials explaining why posterior fossa edema can threaten brainstem function even when the primary lesion is cerebellar.
